I need to repair what the manufacturer calls 'dimple leaks' in my solar heating panels for my pool - but I can't find the right plugs on the secondary market.
The manufacturer recommends using four plugs per leak .
The rubber plugs from the manufacturer cost about $55 per 100 count (which will only fix 25 leaks), so I was hoping to second source cheaper plugs.
After diligently searching, I found 'very similar' plugs for $5 per hundred count (see below).
These shorter plugs work - but because they are a tad too short, they are commensurately harder to install properly.
My basic question to experienced users is:
Q: Do you know where I can get rubber stoppers that are at least 7/8" long, while still being 1/4" on one end, and 1/8" on the other end?
Note:
The closest I can find at McMaster-Carr (PN 6448K88) is 3/4" long, 1/4" on one end and 1/8" on the other end.
Likewise with RubberDynamics.com (PN TPE0250-0750) & WidgetCo.com (PN 7-R000000-EPDM-RS).
